WebDWI is most applicable when the tissue of interest is dominated by isotropic water movement e.g. grey matter in the cerebral cortex and major brain nuclei, or in the body—where the diffusion rate appears to be the same when measured along any axis. However, DWI also remains sensitive to T1 and T2 relaxation. WebADC value decreases signal intensity at DWI, whereas a low ADC value increases signal intensity at DWI. The changes in ADC are inversely correlated with the changes in tis-sue cellularity: a low ADC indicates areas of restricted diffusion in highly cellular areas, whereas a high ADC value indicates areas of diffusion in less cellular areas [1 ...
